REGULATOR-FUC'ET FOR LIQUID UNDER PRESSURE.

SPECIFICATION forming part of Letters Patent No. 563,952, dated July 14, 1896.

Application lerl April 2, 1896. Serial No. 585,884.. (No model.)

To a/ZZ whom it may concern:

Be it known that I, SAMUEL C. FEEELS, a citizen of the United States, residing at Hollister, county of San Benito, State of California, have invented an Improvement in Regulator-Faucets for Liquids under Pressure; and I hereby declare the following to be a full,

4 clear, and exact description ofthe same.

' conical valve-plug. adapted to engage with a correspondingly conical seat, whereby the liquid is permitted to pass around said valveplugin a thin sheet or lm, and in connection with said plug a circumscribing wall over which the liquid overflows from laround the plug in a thin sheet on its passage to the discharge.

The object of my invention is to provide a simple and effective faucet,by means of which the pressure in the vessel from which the liquid is withdrawn is reduced and held in check in such a way as to permit the liquid to flow without undue foaming or the presence of the unrestrained gas.

Referring to the accompanying drawings, Figure 1 is a longitudinal section. Fig. 2 is a horizontal section,the plug B being omitted. Fig. 3 is a cross-section.

The shell A of the faucet has an inlet-passage o, and an outlet or discharge passage a. In the shell is a conical seat c2, with the lower portion of which the inlet-passage a communicates through a port as.

B is a conical valve-plug, seated accurately to the seat a2 and adapted by its reciprocatory movement in said seat to close the port c3 and to open it again and form an annular or circumscribing space between the seat a2 and the periphery of the valve-plug. This plug is reciprocated by means of a usual stem C, operating through suitable connections in the ordinary manner, and connected with the valve-plug in any suitable manner, as by the ball-and-socket joint shown.

The seat a2 is circumscribed by a wall D, the upper edge of which bounds the upper end of the seat, and said wall forms within the shell an outer circumscribing space or vacancy d, the lower portion of which communicates with the discharge-passage a' of the shell.

Suitable means are employed, in connection with the shell, for coupling or connecting it with a pipe leading to the vessel containing the liquid under pressure, or the faucet may be directly connected with said vessel, as the case may be.

The operation of my faucet is as follows: Vhen the stem C is screwed down, the valveplug B fits closely in the seat c2 and cuts off a communication through the faucet. When now the stem C is screwed up and the valveplug B is thereby raised, a narrow annular circumscribing space is formed between the periphery of the plug and the interior wall of the seat, and the port a3 is opened, so that the liquid now vpasses through the passage c, port a3, and into the circumscribing space around the valve-plug, and said space being anarrow one theliquid surrounding said plug is in the form ofa thin film or layer which prevents undue pressure of gas and has no tendency to become agitated, so that it Iiows through said space freely enough, but without foaming. This effect is materially increased by the circumscribing wall D of the plug-seat, over the top of which the liquid from the space around the plug flows still in a thin stream or film and over its whole top and down the outside of said wall to the discharge-passage a', issuing therefrom without foaming and without the escape of that quantity of gas which, if unrestrained, would accompany the liquid and cause it to foam.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a regulator draw-off faucet for liquids under pressure, a wall in the shell thereof having its outer surface separated from the shell by a space which communicates with the exit or discharge of said shell, and its inner surface forming a conical seat which communicates with the inlet-passage of the shell, and a reciprocating conical valve-plug tted to and normally circumferentially closing IOC) against said seat to control the inlet communication and the passage of the liquid to the seat around said plug and over the Wall top to the exterior space and discharge-passage- 2. A regulator-faucet for liquids under pressure, consisting of a shell having an inlet and an outlet passage and an interposed conical seat in said shell communicating with the inlet-passage, a reciprocating conical Valveplug circumferentially ittecl to said seat and adapted to normally close the communication with the inlet-passage and to open it again and form a circumscribing narrow passage around and parallel with its circumference hand.
